近年来,川东南用杂交水稻,川东用中籼“南京11号”、“盐籼203”,川西北用迟熟早籼“蜀丰1号”等品种培育再生稻,在一些社队获得较高产量。由于再生稻具有生长期短、日产值高、省工省种等优点,目前已逐渐引起各地重视。头季稻的留桩高度直接影响再生稻的利用节位和生育期,是关系到再生稻稳产高产的重要技术。现根据四川省农科院作物所、江津地区农科所等单位的研究和一些社队的成功经验,就我省再生稻留桩高度的几个问题简述如下。
In recent years, hybrid rice in southeastern Sichuan, East Sichuan with medium indica rice “Nanjing 11”, “salt indica 203”, northwest Sichuan with late maturing early indica “Shu Feng 1” and other varieties of ratooning rice, obtained in some commune teams Higher yield. Since ratooning rice has the advantages of short growth period, high daily output value, and provincial and provincial species, it has gradually attracted attention from all over the world. The pile height of the first season rice directly affects the use of node and growth period of ratooning rice, which is an important technique that is related to stable and high yield of ratoon rice. Now according to Sichuan Academy of Agricultural Sciences Crops, Jiangjin Agricultural Research Institute and other units of the unit and the successful experience of some communes and teams on the remaining rice piles in our province a few problems described below.
